Demand assignment multiple access protocols for wireless ATM networks

A multiple access protocol is a scheme to control the access to a shared communication medium (radio frequency) among various users. Although many access protocols have been proposed and each has its advantages and limitations, very few are suitable for integrated wireless communications. Access protocols can be grouped according to the bandwidth allocation mechanism, which can be static or dynamic, and according to the type of control mechanism implemented. Multiple access protocols can be categorized into three classes: fixed assignment, random assignment, and demand assignment.
